' Be it known that I, CHARLESSH. STENBERG, a citizen of the UnitedStates, anda' resident of Radcliffe, in the county of Hardin and Stateof Iowa, have invented a certain new and useful Oil-Feed for WicklessGil-Burners, of which the following is a specification.

The object of my invention is to provide a reliable oil feed for awickless oil burner of simple, durable, and inexpensive construction.

More particularly it is my object to provide such an oil feed having awick-Siphon to carry the oil from the oil reservoir and drop it into thefeed pipe.

Another Objectis to regulate the carrying capacity of the wick-siphonautomatically so as to produce a flame suitable to maintain a lcertain`predetermined temperature sur-- rounding the burner under varyingatmospheric temperature.

With these and other objects in view, my invention consists in theconstruction, arrangement anci-combination of the various parts of thedevice, whereby the objects contemplated are attained, as hereinaftermore fully set forth, pointed out in my claims and illustrated in theaccompanying drawings, in which:` v

is mounted a funnel shaped casting 2, having an arm 2a. Mounted on thearm 2a is a receptacle 3 having two compartments 3a The compartment 3acommunicates with the compartment' 8b near the bottom to allow oil tolflow from the compartment 3h. into compartment 3a. Mounted oncompartment 3b is an inverted jug 3c which is provided with 'a cork 3emounted on a bail dwhich extends up over the jugm The bail 3d fits intoa forked support 3t which is 4secured to the receptacle 3. Thereceptacle 3 with the jug 3c constitutes the oil reservoir. With the jugvin place as shown in Fig. 2 the oil is maintained in the compartments3b and 3a on a level with the opening in the neck 'of jug. When it isdesired to replenish inverted and replaced in the rece tacle 3.-

When the jug is in place the bailBd 1s shoved down which draws the corkfrom the neck of the jug and allows free flow of oil. The

iow of oil is regulated by the well known principle of atmosphericpressure to maintain the oil level as described above.

-A wick I is mounted in a'tube 5 and extends up from the bottom of thecompartment 3a ofthe oil reservoir and over said compartment wall anddown into the funnel 2 for a pur lose described hereinafter. rlhewick ispre erably made up into 2 or more narrow wicks, each wick held inseparate compartments 5", clearly` shown in Figs. 4f, 5 and 6. Thetubeconsists of two main parts 5 and 5a. The wicks are placed in the art5 and the cover `5a is slipped over from t e top. A removable bail 6 ispro, vided to suspend the tube from the automatic regulator lever or anyother suitable the tube, in that end which extends down into the oilreservoir is preferably successively shorter and is closed andperforated at,5c and 5". 'See Figs. 6, 7 and A small extension, of thatsection of the I These features are explained hereinafter.

To the end Off the horizontal SeCtOn f ber of lever 8 by means of a link10.

the feed pipe burner which absorbs i which tube 5 .iiow of oil litcarries as a lconstant flow ieaiev 1 is connected a burner by means ofthreads A. A bracket 17 supports the feed pipe at this end. An asbestosring T is set in a channel in the base of the the oil and serves as ameans of ignition when the oil is fed `into said channell by means ofthe feed pipe 1 `which communicates,l with said channel by vmeans of thehole' 1S.

The chimney V having an inner tube U sits loosely on said burner. Theinner tube provided with a cap A bracket 11 is secured to the horizontalsection of the feed pipe 1. A thermostat 12 and a pivoted lever 13 whichengages with the thermostat at its free end is mounted on the bracket11."

On theupper end of casting 7 is pivotally mounted a lever 8 havinga'horizontal and a vertical member. 0n the free end of the horizontalmember of lever 8 is hung the by means of the bail 6. At a point betweenthe base and upper 'end of the casting 7 is pivotally mounted a lever 9.The upper end of lever 9 is pivotally connected to the free end of thevertical mme he lever 9 is adjustably connected to the upperend of lever13 by means of a rod 14 having a threaded ,member 15 on which is fitteda threaded bur 16.

Having described the mechanical construction of the diiferent parts, Iwill now explain how the different parts function individually and incombination.

Presuming that the oil reservoir hasa full supply of oil and that allparts are in place as shown in 1. The wick-Siphon opposite endr of thehas a greater carrying capacity the lower constant level in 8a where thereceiving end of the wick-A siphon is submerged .in the oil. It is awell known fact that a wick is not nearlyY so subject to Vclogging orvariations in the valve commonly maintaining a minute and of oil for aheater of this kind.. It may be said in this connection that the burner,the thermostat with the actuating connections and the jug with itsattachments are of ordinary construction, hence I deem it unnecessary togive minute used for such Q explanation oftheir functions.

If it`should be desired to reduce theilame the wick-Siphon is raisedslightlyy which reduces the flow of oil, as a result of thewell knownprinciple of a ,caution against the burner where it is Ithat the wickscan always Siphon whose capacity is in proportion to the length of thedischarge end extending below the level of the furnace of the liquid.VAs an additional means lof controlling the flow of oil by raising andlowering the wick-Siphon I divide the wick into 2 or more parts and makethe different parts of different lengths so that when the wick-Siphon israised to a certain height one of the shortest parts will become freefrom contact with the oil and thus reduce the flow of oil. As the wick-Siphon is withdrawn farther each successive part will be withdrawn fromthe oil and lessen the flow of oil. And vice versa. when an increase ofthe flame is wanted. As a precaution against extinguishing the flamewhen the automatic regulator is used to regulate the flame I provide anextension which will extend down into the oil when all other parts arewithdrawn and maintain a minute flow of oil. As still another additionalmeans of controlling the flow of oil by raising an lowering thew-ickesiphon YI taper the discharge end. The flow 0f oil is greater whenthe whole width 0f the wick is extending below the oil pered end'extendsbelow. As a further preextinguishing the flame when the automaticregulator is used I 'extend one of the wick parts with a tapered enddown so that it willA extend below the oil level when the actuatinglever 0f the automatic regulator yon which the wicksiphon is suspendedreaches the extreme height of movement.

It can be seen that theJ wick-Siphon will maintain any jdesired quantityconstantly without any perceptible varia- It can also be seen that thethermostatic level than when only the taflow of oil regulator willcontrol the position of the Y wick-Siphon so as to maintain any desiredtemperature surrounding the burner..

To place the wicks in the tube the cover 5a is slipped off upward and asuitable wick is placed ineach compartment. I have provided a closed endfor each compartment so be placed in accurate position.- The closed endsare perforated at 5 toadmit the oil tothe wicks. TheY tube is alsoperforated on the sides near the end 5d to admit oil to the wick.

lSome changes may be made in the construction and arrangement of theparts of my device without departing from the essential features andpurposes thereof, and it ismy intention to cover by my claims anymodified forms of structure or'use of mechanical equivalents, which maybe reason# ably included within their scope.
